I am changing a few things in the story of Liefully and his late lover, Tony Stark of another universe. I’m doing this for the reason being that it doesn’t make sense for him to have a culture shock when coming to Midgard when he lived with Stark for maybe 20 to 30 years on Midgard long before the events that occurred in the movie, Thor. So my solution is going to be a simple one. Since it’s an alternate reality, the technology was super advanced. I’m going to pull from my concepts that I created for an original story plot I named Chrysanthia, and say this particular AU Stark was from the 4400’s, so there were advanced technologies and an advanced people that Liefully had to blend in with. The culture of the 4400’s is EXTREMELY different from the culture of the 2000’s. So this is my explanation why Liefully is basically having to “re-educate” himself on Midgardian culture. Because the culture he encountered in Stark’s universe was vastly different from the culture in his present universe.
I will now write my headcanon for Liefully and his late lover Stark currently:
Once upon a time ago, long before Liefully discovered he was a Jotun, before he fell from the bifrost, before all of that, he one day tripped into a portal that landed him into another reality. Before this event, Liefully had an extremely limited knowledge of alternate dimensions. He discovered, to his surprise, there was a Thor in this realm, but there was no Loki. The Loki in this alternate reality had died and failed to come back to life. Liefully decided to take that Loki’s place for a time, since he was unable to figure out how to get out of the alternate reality that he managed to stumble into.
Liefully found what happened to the Loki in this universe a bit interesting. This universe, he had soon discovered upon arriving, was a futuristic universe, though many of the entities that existed in Liefully’s realm existed in this universe’s present, which was another thing Liefully found curious. Liefully discovered the Loki in this particular universe had slaughtered Odin to gain power of Asgard, though Thor stopped Loki from obtaining the throne. He also discovered this Loki tried to raise an army from first Niflheim, by making a deal with “Hela,” as she was called in this universe, to take over Muspelheim in an effort to bend them to his will. The action of going into Muspelheim with an army of dead souls lead to Loki’s own death, and since he failed in his deal to Hela, she refused his exit from Niflheim.
Thor of this universe took Liefully to Midgard and introduced him to various others, such as Stark, Deadpool, Spider-Man, and the X-Men. Liefully learned of Thor’s relation to each individual, who Thor got along with and who he didn’t. Liefully soon discovered that Thor and Captain America both really hated Stark, there was a lot of in-house fighting among the Avengers. (In this universe, the Avengers consisted of Stark, Captain America, Hawkeye, Hulk, Antman, the Wasp, and the Black Panther. Spiderman and Wolverine sometimes tagged along, though not as much.)
After some time, Liefully and Thor got into a sibling fight of some kind, so Liefully decided to get back at Thor by making his life awkward. Liefully took possession of Sif’s body because she was Thor’s true love. Thor became upset, however there was nothing he could do to stop Liefully because harming Liefully would harm Sif. So he had to comply to Liefully. Later on, Liefully and Thor went to a bar where Tony, then very drunk, began to hit on fem-Loki, not knowing it was Loki. Thor became increasingly upset because he hates Stark, finding him rather idiotic and chaotic, despite supposedly being a genius. Thor threatened Stark for hitting on fem-Liefully, though Liefully told Thor to back off. He wasn’t interested in Stark, however seeing how upset Thor got by Stark hitting on Liefully-possessing-Sif’s-body, Liefully decided to spend more time around Stark just to intentionally piss Thor off. Liefully then seduced Stark, made Stark interested in Liefully to ensure he could upset Thor.
What Liefully soon discovered was Stark was rather chaotic and destructive because of his constant state of drunkenness. Most found that chaotic and destructive behavior obnoxious and despised Stark for his dangerous actions and idiotic ramblings. However, Liefully only found amusement in them. Perhaps it had something to do with Liefully being a playful god of mischief, perhaps not. Nonetheless, Liefully became increasingly attached to Stark’s destructive patterns. This particular Stark was well known to be so often drunk that he would so often accidentally crash through buildings, fall into cars, blast holes through walls, etc. He also rambled on, saying lame pick up lines, cheesy things, rather blunt and inappropriate jokes at times, and was a constant flirt. Liefully soon came to absolutely love it.
Soon Liefully convinced the often inebriated Stark to go out and destroy things with Loki, or cause a bit of mayhem and mischief in various cities. Stark, in nature, was not a bad guy, though he was easily manipulated and misguided to do bad things when he was drunk. Whenever he did sober up, he would get in fights with Liefully about the things they did and would try to reason with Liefully that it wasn’t right. Liefully often found ways to calm him down, either through words or seduction. If not, Stark would just storm off and vent for a while and eventually come back.
Over time, Liefully settled down with Stark and stopped driving him to be so destructive. The destructive behaviors were only interesting for so long, and soon Liefully became more interested in Stark as a whole. Over time, Stark too began to change and stopped focusing on the fact that his girlfriend was appealing to look at and was really starting to appreciate Liefully for Liefully’s personality and the care and dedication that Liefully gave to Stark, where many others would not.
Liefully was pretty open and honest with Stark after a while. While Liefully had told Stark since the beginning that he was actually Loki possessing Sif’s body, there were many other things Liefully kept to himself and didn’t even tell the Thor of this universe. Liefully went into explaining the situation he got in, telling Stark he was a Loki from a different universe and accidentally got trapped in Stark’s universe to discover the Loki of his universe was long dead. Liefully also went on to explain the situation in his own universe, telling Stark he was married to Sigyn for several hundreds of years and was currently royalty in Asgard, or at least he was before he disappeared. Stark was upset to hear Liefully was already married and felt cheated in some way and didn’t talk to Liefully for a short time. Eventually Stark came around and the two of them simply did not speak about marriage together or even the possibility of having children, which neither even wanted anyway.
Liefully spent somewhere around 20 to 30 years with Stark. He had first encountered the mortal when he was still pretty young. Their relationship was pretty open and carefree, despite many of the initial protests of Thor, the Avengers, and various other super-beings and friends of Stark who knew of Loki’s negative antics. Though aside from the protests from such people, Liefully and Stark didn’t face much other opposition and the only enemies they ever really worried about were Stark’s enemies, which Liefully would often provide help in defeating from time to time.
Despite growing to love each other increasingly over time, they were not without their quarrels. One time, specifically, they entered another verbal fight that eventually led Stark to storm out furiously to go drink, which was something he typically did after getting in a fight with Liefully. Though hours passed, more so than normal, and Liefully started to worry. When it became morning, Liefully called Stark Industries to see if Stark had simply refused to come home and gone to work later. They told Liefully he wasn’t seen that morning. Liefully commanded Jarvis to track Stark via his phone or his suit and Jarvis supplied Liefully coordinates to a remote off-mountain location. Stark had gotten drunk and drove. Liefully could tell by his location, he was driving back home and had crashed his car over the ledge of the mountain. He was apparently too drunk to save himself. Liefully was devastated and also blamed himself for what happened to Stark. He figured had he not gotten in a fight with him, Stark would be all right.
He may have found Stark dead, though no one suspected foul play. Jarvis served as a good alibi for Liefully and Stark’s car had some manner of tracking device that indicated when he crashed and subsequently plummeted to his death. Liefully attended Stark’s funeral that same month along with various others. Even though he was not married to Stark, everyone acknowledged that Liefully was close to him, extremely important to Stark and Stark to him. It came to Liefully’s surprise that he was the primary beneficiary listed for most of Stark’s assets, some specific things were named to others and Liefully had no objections with Stark’s decisions in his will. Liefully spent about three months living in Stark’s home before he decided he couldn’t stand it anymore—the quietness, the emptiness, being surrounded by things about Stark but not being able to be with him—and needed to leave. Pepper and Happy aided Liefully in moving out of Stark’s home, arranging a new place for him to start over. About half a year after he moved out, Liefully discovered another portal back into his universe.
To his surprise, Liefully discovered that only 3 days passed in his universe that he missed. Asgard did not miss Liefully as he sometimes disappeared unannounced for several days. No one asked where he went and he didn’t tell anyone what happened in the other universe. Eventually he pushed the memories back in his mind and resumed life in his universe as he had before he left it. He did not think about Stark again for many years, and only did when he saw Stark’s face on Midgard, his Midgard, during the events of The Avengers movie. There was a certain reserve he kept when interacting with Stark, though it was hard to contain a smile, hearing his voice again after so long. Despite this, this Stark’s behaviors were quickly noticeably different from that of the Stark he knew and Liefully only felt a certain disappointment or insult toward this second Stark.
